An advanced Langmuir probe for plasma diagnostics

Routine monitoring of the I-V plasma characteristic by the Hiden ESPion probe gives direct information relating to plasma stability and reproducibility. Automatic real-time extrapolation of plasma parameters gives detailed information on plasma properties for use in characterisation and uniformity monitoring.


The ESPion system employs Orbital Motion Limited (OML) and Allen Boyd Reynolds (ABR) as standard plasma analysis models.

The Hiden automatic Z-drive provides for spatially resolved measurements across the plasma volume. The standard Z-drive translation options are: 300, 600 and 900 mm.
